Children with sporotrichosis may present more frequently with a solitary ulcerative nodule rather than the classic lymphocutaneous form seen commonly in adults. We report a pediatric case of localized cutaneous sporotrichosis presenting as a solitary ulcerative plaque on the abdomen.
A 2-year-old white girl presented with a 2-month history of an enlarging ulcerative lesion on the abdomen. The lesion began as an erythematous papule that quickly enlarged and ulcerated despite topical and oral antistaphylococcal antibiotic therapy. A methicillin-resistant Staphylococcus aureus infection was then suspected by her pediatrician, yet a surface wound culture yielded no bacteria, and empirical treatment with trimethoprim-sulfamethoxazole and rifampin resulted in no improvement. There was no known history of trauma to her abdomen; however, she was an active toddler who lived with her parents in the rural Midwest on a cattle farm where her father grew hay.
